My wife wants a car and she pretty much fell in love with an A4 cabriolet. Plan is to buy 2/3 years old. We took one out from the dealer at the weekend and she was very happy, but would like an automatic gearbox. I managed to get out of work early today and took both a 3.0 TDI quattro and a 3.2 FSI quattro today (different dealers) and liked them both! So would she. The petrol car is 6 months older and has done 20k less miles, but is 2k more expensive. Opinions on the two cars please? I'm in a position to buy one tomorrow. Both are fully loaded. Roughly what should I be expecting from the dealer as a % off the sticker price so I don't get taken for a ride (and how low should I start the haggle)? No trade in, might take out the lowest finance possible to get the two years free servicing deal.
